- Biometrics can be an effective technology for aviation security if properly implemented, but requires careful planning and management to be successful.
- Key factors for a successful biometric deployment include having clearly defined security objectives, starting small and gaining successes before expanding, and ensuring effective user education and buy-in.
- Biometrics are one part of an overall security system and must be integrated with operational processes and personnel to be effective. Proper project methodology is essential.
